HEPA Filters: What They Do and Why the Bedroom Comes First

By The Lungora Team · Published · Reviewed September 23, 2026

Few wellness purchases rest on physics this simple: air passes through a dense mat of fibres and the particles do not.

Quick answer: A true HEPA filter traps 99.97 percent of particles at 0.3 microns, covering dust, pollen, dander and smoke. Size the unit to the room using its clean air delivery rate, and put it where you spend eight hours a night.

The bigger picture

Air is the part of lung health you can actually engineer. Age and genes are fixed; what you breathe at home is not. Attention to HEPA air purifiers works for you every hour of the day, silently, which is more than any product can say.

Inside the filter

Large particles crash into fibres, mid-sized ones are intercepted, and the tiniest drift into fibres by random motion. Particles around 0.3 microns are hardest to catch, which is why the standard is set there.

Getting the size right

Look for the CADR figure. A rough rule: the smoke CADR should be at least two-thirds of the room's floor area in square feet. A small unit on its lowest setting in a large room achieves little.

What it will not do

Gases, odours and VOCs pass straight through unless the unit also has activated carbon. Avoid anything that generates ozone. Filters saturate; plan on replacing them every six to twelve months.

Four things to try this week

  • Bedroom first; that is where the hours are.
  • Doors and windows closed while it runs.
  • Change filters on the maker's schedule.
  • Skip ionisers and ozone generators.

Mistakes we see often

  • Covering smells with fragrance rather than ventilating.
  • Leaving filters until airflow visibly drops.
  • Assuming air that looks clean is clean.
  • Choosing a purifier rated for a smaller room than yours.

Where Lungora fits

We prefer being useful to being persuasive, so here is the precise version. A capsule does not alter the fundamentals of HEPA air purifiers. Lungora offers a five-second habit built on nutrients that have NIH fact sheets of their own. The men and women who like it report gradual, modest changes in energy and sleep. The ones who do not get their money back inside 60 days.

Turn our bottle around and you find: take one capsule daily with water; not for pregnant or nursing women or anyone under 18; consult a physician if you take medication; six ingredients, magnesium first at 80 mg. No supplement is FDA approved and ours claims no such thing. You can read more about how Lungora works and Lungora benefits on the Lungora site.

A seven-day start

Day one: check your local air quality index. Day two: find out how old your furnace or purifier filter is. Day three: buy a cheap hygrometer. Day four: run the extractor every time you cook. Day five: air the bedroom for ten minutes if the outdoor reading is good. Day six: vacuum with a HEPA machine. Day seven: note what changed. Progress on HEPA air purifiers is built from steps this small.

When to see a doctor

Better air helps everyone, but a symptom still needs a proper look. A cough, wheeze or tight chest that persists after you have cleaned up your home's air, or eases on holiday and returns at home, is a pattern worth describing to your doctor. Sudden breathlessness, chest pain or blood in sputum need urgent care.

In brief: HEPA air purifiers

  • A true HEPA filter traps 99.97 percent of particles at 0.3 microns, covering dust, pollen, dander and smoke.
  • Inside the filter: start here.
  • What it will not do: where small daily choices show up.
  • A capsule such as Lungora is optional and comes after medical care, never instead of it.

Frequently asked questions

Do HEPA purifiers work?

Yes for particles, when sized for the room. They do nothing for gases unless they carry a carbon stage.

Are candles bad for indoor air?

They release fine particles and volatile compounds. Occasional use with a window open is minor; nightly use in a shut room adds up.

Does Lungora detox the lungs?

No capsule can. Airways clean themselves. Lungora supports circulation, cellular energy and antioxidant defence around them.
